Stillwell terminal in Coney Island is the second epicenter of the system after Broadway Junction Both of these have seen many changes over the years Here are a few that I noticed while looking at some old picture of Stillwell
The double slip switches are gone and the track has been reconfiguered here
The West End tracks used to connect on the South side to the Culver ( Funny its the North side of the Culver ) The West End ends at bumper blocks now
The gas tanks are gone
The Riviera looks a lot different
